Process GC Maintenance and Troubleshooting Tips
For process gas chromatographs to perform reliably, they require frequent data validation and proactive maintenance. Below, we discuss some of the diagnostic tools and issues you need to know about when it comes to process GC troubleshooting and maintenance.
Tip #1: The Importance of Verifying Your Process GC’s Flows
Checking your process analyzer’s carrier gas and detector flows is often a good first step when troubleshooting process GC problems.
Learn More Tip #2: Process GC Problems? The Answer is in Your Chromatogram!
Most people don’t realize that the chromatogram is the most powerful diagnostic tool we have for troubleshooting process GCs.
Learn More Tip #3: How Do You Know if Your Process GC is Generating Accurate Data?
Process GC owners must somehow verify on a regular basis that their GC data is suitably accurate and precise. Implementing a multifaceted analyzer validation program is the key.
Learn More Tip #4: Spotting Interferences
There are numerous forms of interferences, all of which can hinder or seriously impair the accurate quantitation of your analytes and lead to inaccurate process GC data. Learn what to look for.
Learn More Tip #5: Why Leak Checking is So Important
Large leaks of carrier, detector or sample gases within the process GC oven can be catastrophically dangerous – and even small leaks of carrier gasses can seriously impair your analyzer. Learn what you can do to prevent problems.
Learn More Tip #6: Why Have My Peaks Shifted?
There really are only a few reasons why peaks shift and do not appear on your chromatogram at their expected retention times. Find out what they are.
Learn More Tip #7: Why Validation Systems Alone Don’t Solve Your Analyzer Problems
It’s important to realize that validation systems can only detect analyzer problems, not fix them. Unfortunately, figuring out the underlying cause of a process GC’s failure is usually the most difficult part. Learn what you can do.
